I 'm trying to find some info on a yoke on my ford 9". It is not the standard 1-9/16 x 3-1/4 or 1-9/16 x 3" nor 1-7/16 x 2-7/8 u-bolt centers but measures 1-7/16 x 3-1/4". Any help is greatly appreciated

If I am reading this correctly, you are telling us that your u-bolts have threaded ends 1-7/16" apart instead of 1-9/16". And the distance from one u-bolt to the opposite u-bolt is 3-1/4" instead of 3" or 2-7/8". Am I reading this correctly?

Clean your yoke thoroughly, then look for casting numbers on the yoke. Usually they are in the saddle(s) that are 90 degrees rotated from the cups. Sometimes those numbers help identify yokes.
